As a big time earth enthusiast, I think it is just absolutely fascinating, all of the incredible changes that this big world has gone through over the millions and millions of years and how it has effected life on Earth. And to think that it’s still continuing to go through a lot of changes today. This crazy world is nothing short of remarkable. ❤🌎🌍🌏❤
A happy mother's day to you, Rachel. And as always, thank you for your passion in learning and the time you take to make all these videos! It's refreshing and inspiring, and always has me thinking and asking questions.
I was going to say that I was following along fairly easily, because there was not much new from what i learned 50 years ago.....until you hit me with the Chesapeake Bay impact event in the late Eocene......Not sure when it was discovered, but nobody mentioned anything about it back then. PS....1983 was way after my Geology studies.
OMG that is such a hard question! Just one time?? haha I think I would either go to the Ediacaran (just before the Cambrian when large animals were evolving), or to the GOE but I would want to see what happened before, during and after it which is like a half a billion year time span hahaha so I am not sure if that counts, but my other option would be to go to long before the GOE (with an oxygen tank) around 3.8 billion years ago to see if there really was life by then and what kind of life it was.... OOOHH Or I would actually go to whenever the origin of life on earth was so I could see whether it was a subsurface or surface enviroment! OMG this is too hard!! 🤣
As a geography student who just passed Earth History exam (using the infamous 4th edition of Earth System History) I can say this was a very good summary, well done!
Wow the orogeny of the Rockies!!! A big subject thanks for covering it. Maybe you could discuss how the Rockies were cut down by erosion. Farallon Forever. Currently surfing the Eastern Pacific Plate to San Francisco and Alaska wish me luck.
@@GEOGIRL Thanks! Me and my neighbors live on the west side of the San Andreas transverse fault so we are headed north in Geologic time. I set my watch to Eocene Time so I don’t have to fiddle with it every October and April. I hope to be North of Oregon before the basin and range province gets flooded with basalt and becomes the Las Vegas Large igneous province like the Siberian Traps and triggers a mass extinction event.
Do geologists have an accurate estimate, Rachel, of how long it took for Earth to recover from the KT extinction event? I'm not talking about the number of species rebounding but basically how long it took for the surface to become reasonably habitable again.
Totally irrelevant to the geology, but I can't help but wonder what Jacques La Ramée, the early 1800s fur trapper that the Laramide is indirectly named after, would think about his name being immortalized by geologists centuries later for a process he probably couldn't have even imagined.
Nice video interesting 🤨 age of birds no more dinosaurs 🦖 the hell pig lived during this time and the notoungulates rhinos and elephants no humans during this time
Basic design communication . Show epochs old to young left to right in reading order, not backwards. Also some of those Maps, particularly the Chesapeake Bay, map are nearly impossible to read, just a jumble of lines on top each other, unclear what was land and what was water. And the usual Encyclopaedia Brittanica on every single Powerpoint slide with text and pictures crammed wherever they might fit. Less is more. Divide the content into clear well laid out slides. Each with a clear numeric date, not just the hard to remember epic h/era names. It doesn't have to be all on one page. But overall great content, despite it is hard to absorb.
Thanks for the tips, for live lectures, I usually don't include so much text on the slide, but I've heard from many viewers that they pause and take notes, so I try to keep the full picture of text on the slide rather than cutting it down to the point where it would only be understandable within the context of what I am saying. But I can certainly make more slides with less on them. In my more recent videos, I have been going bullet point by bullet point to cut down on the amount of text showing at once so it's easier to follow. Also, as for the figures, I couldn't agree more. Unfortunately, I can spend hours on end searching for good figures and graphics and sometimes just don't find them, which was the case for the Chesapeake Bay figures. And as for the time scales, many scientific papers publish time going from oldest to youngest (which is what I like as well), but many do the opposite as to increase the number going to the right which is normal for typical numerical x axes, so sometimes I am not able to find the figure I want with the time going from oldest to youngest. These are not figures I've made they are figures from scientific papers and textbooks, but hopefully someday I will have the time and resources to make my own or hire a graphic designer that can do that ;D Anyway, thank you for the feedback, it is much appreciated! These are definitely things I will aim to keep improving ;)
So nothing interesting outside of North America? Didn't Asia and Europe connect together to form Eurasia? (not sure if Africa would join in the Paleogene to form Afro-Eurasia just yet)
Yep, but all this happened quite a long time before the Paleogene. Eurasia formed during the merging of major continental landmasses, Siberia, Kazakhstania, and Baltica, with Laurentia (the North American craton), to form Euramerica around 350 million years ago, in the mid Paleozoic Era. Pangea eventually brough everything together around 250 million years ago at the end of the Paleozoic Era, and then everything has been splitting up to its current placement since then. The first to split was Eurasia from North America and Africa ~200 to 150 million yrs ago and then South America from Africa ~150 to 100 million yrs ago. Then Austrailia and India finally split from Antarctica just before and during the time frame of video (the Paleogene epoch) :)

Couldn't agree more ;D 💚💙💚
@@GEOGIRL You’re the best Rachel. I’m glad we’re always in agreement with each other. You’re absolutely amazing my friend. 😊❤😉👍
@@Smilo-the-Sabertooth Right back at you!! :D
@@GEOGIRL ❤👍
Thank you for the effort you took fo the video. I love your content
Thank you so much! So glad you enjoy my content ;D
Also, I love your profile picture :D haha
Very nice video..🙃🙃👌👍
Thanks so glad to hear you liked it :D
@@GEOGIRL most welcome..🙃🙃😁
Never thought to see such good video in TH-cam ❤💕💖.
Aw thank you!

Thanks so much Chad! I appreciate your loyalty and support so much! And I am so glad you find my videos inspiring & thought provoking ;D
OHHHHH
So she's a mother?
So that means she most likely taken?
Ah shucks
@@MrZackavelli Nope, not a mother, not even in a relationship lol
Just a PhD student spending all my time working ;D
@@GEOGIRL good, boys are trouble, i know, i was one once. ;-)
So beautiful .. your look..😁👌👌
Thank you ;)

It is crazy how much our understanding of geology has changed since the 70s-80s! ;)
If you could visit the Earth in the ancient past, when would that be?
I ❤️ GEO GIRL

so awesome explanation 😊
Thank you! ;D
Literally wonder filled videos.
Nice colour of your tshirt 👕
Geogirl, you're so freakin' informative, but I just have to comment on how gorgeous you are
Don't ever stop releasing videos
Thank you so much ;) I appreciate your support and kind words!

Where was the area of Nevada in all of this?
There are some researchers who are suggesting that the Laramide was caused by terrane accretion
Good morning geo girl..🌅🌅
Good morning! ;D

Hello geo girl
Hi there, how are you? ;)
@@GEOGIRL i am good and you
No one hardly speaks of the origins of Europe during this period.

You got a cute tortoise kitty going on! Whats her name?

Goodamn pointing.
Haha, I am sorry, sometimes I get a little crazy with it, I am trying to dial it down in more recent videos :)
